Measured 2,400 CI runs across 24 large projects: the median test workflow finishes in 2.2 minutes

Including queue time is the right call and I would go further: it is the only number that matters to the person waiting.

We spent a quarter optimising a test suite from 14 minutes to 9 and the perceived improvement was nothing, because peak-hours queue time was 6 minutes and we had not touched it. Moving to a larger runner pool did more for the team than the optimisation did.

Measure what the developer waits for, then decide which half to attack.
